It would be great if ConTeXt supported: \mainlanguage [serbian] [script=latin | cyrillic] as well as \mainlanguage [english] [variant=american | british] etc. This is what Polyglossia does and I find it nice.

How to sort in Lua using locale?
by Mojca Miklavec 12 Jul '10

12 Jul '10

Hello, I would like to create a document using some functionality that is pretty close to creating an index, but the built-in index creation code doesn't suffice. My main question is: how do I sort strings using the built-in sorting rules for the current language? Here is an example with a table of names: names = { {first="Hans", last="Hagen"}, {first="Hartmut", last="Henkel"}, {first="Taco", last="Hoekwater"}, {first="Caron", last="Haček"} {first="Ančka", last="Car"} {first="Ana", last="Car"} {first="Anita", last="Car"} {first="Matija", last="Čop"} } and I want to print out the following: \section{C} \person{Car}{Ana} \person{Car}{Ančka} \person{Car}{Anita} \section{Č} \person{Čop}{Matija} \section{H} \person{Haček}{Caron} \person{Hagen}{Hans} \person{Henkel}{Hartmut} \person{Hoekwater}{Taco} The following code works for English and needs a fix to respect local sorting rules. I would be grateful for any hint before reinventing the wheel (the hint can also be a pointer to the right line of ConTeXt source code that does the sorting; I was a bit lost in the code). \mainlanguage[sl] \setuphead[section][style=\bf,before=\blank,after=,number=no] \def\person#1#2{\hbox{{\sc #1}, #2}} \starttext Code that needs fixing: \startluacode names = { {first="Hans", last="Hagen"}, {first="Hartmut", last="Henkel"}, {first="Taco", last="Hoekwater"}, {first="Caron", last="Haček"}, {first="Ančka", last="Car"}, {first="Ana", last="Car"}, {first="Anita", last="Car"}, {first="Matija", last="Čop"}, } -- this should sort with local sorting rules; how? function sort_names(a,b) if (a.last == b.last) then return a.first<b.first else return a.last<b.last end end -- this is extremely ugly and needs to be fixed -- with some UTF-8 library function first_letter(str) if (string.byte(str,1)>127) then return string.sub(str,1,2) else return string.sub(str,1,1) end end table.sort(names, sort_names) for k,v in pairs(names) do -- nested tables would also be an option; but are not required if (k==1) or (k>1 and (first_letter(names[k-1].last) ~= first_letter(v.last))) then tex.print(string.format('\\section{%s}', first_letter(v.last))) end tex.print(string.format('\\person{%s}{%s}', v.last, v.first)) end \stopluacode \crlf\crlf Desired result: \section{C} \person{Car}{Ana} \person{Car}{Ančka} \person{Car}{Anita} \section{Č} \person{Čop}{Matija} \section{H} \person{Haček}{Caron} \person{Hagen}{Hans} \person{Henkel}{Hartmut} \person{Hoekwater}{Taco} \stoptext Thanks a lot, Mojca

Example ConTeXt document: PS output
by Michael Talbot-Wilson 12 Jul '10

12 Jul '10

I've just installed ConTeXt "minimal" and had a look at "ConTeXt, The Manual". I typed in the example document that starts at the bottom of page 13 (called it eg.tex) and ran context. It produced the file eg.pdf and I notice that it ran luatex with the option "--backend=pdf". Thanks, those who have done massive amounts of advanced work on ConTeXt and luatex, huge projects which are costing me nothing. But, I have a problem. I have a PostScript printer. I'd prefer not to have to run pdf2ps. How can ps output be produced directly? "context --backend=ps eg" doesn't do it and there is nothing about --backend or other options in the index, of "ConTeXt, The Manual", as far as I can see. There's no Reference/en/backend on the wiki.

horizontal alignment
by Michael Goerz 11 Jul '10

11 Jul '10

Hi everyone, I'm trying to do some horizontal alignment, for typesetting poetry. There are lines that are continuations of the previous line, and should be aligned to the end of that previous line. Currently, I'm doing this by using \phantom text, which for some reason I also have to wrap into an \mbox to avoid a line break. As an example: \startlines here we now see you ~~ already in grief as you see ~~ yourselves ~~ as the last of the lasts we are mirrors of your consciousness \mbox{\phantom{we are mirrors of your consciousness} as you see the end} and you see us ~~ deep in the spring of the universe seeing you deep ~~ in the gravity well of the heat death we are dying ~~ in the spring as we watch you die we are grieving in the spring as you begin to grieve for all we are talking about bone-dry at the bottom of the well of time we are already parched \mbox{\phantom{we are already parched} for time is transparent} and we are all rats in the glassy \mbox{\phantom{and we are all rats in the glassy} labyrinth of time. \stoplines How would you solve this kind of problem? I've considered defining a macro \BrokenLine[line1][line2] that does the above. But, there are also instances where there are two or more lines as a continuation of one previous line. Maybe there is a possibility to mark a horizontal position temporarily, and then jump to that position later? Thanks, Michael

Better support for Croatian in lang-sla.tex (patch included)
by Vedran Miletić 10 Jul '10

10 Jul '10

Hi, I made some modifications to lang-sla.tex that improve support for Croatian language (quotes, quotations and translations). Hope this can be included in ConTeXt. Regarding translations, I assume existing were done by Mojca, and they are certainly much better than Slovenian tranlsations that I would make :-) -- Vedran Miletić

m-barcodes error
by Michael Green 09 Jul '10

09 Jul '10

I can’t get the example in the m-barcodes module to work. I have no urgent need to print barcodes; I was just curious. I'm writing in case I found an easily corrected bug. The release notes from 2010.05.08 call this module mkiv only. But according to the log, the file m-pstricks.mkii is used. And that seems to be the proximate cause of the error. mjg ------------------------------------- ConTeXt ver: 2010.06.23 12:45 MKIV fmt: 2010.7.6 int: english/english ------------------------------------- command: context "barcode-test.tex" ------------------------------------- file: barcode-test.tex \usemodule[barcodes] \starttext % this is copied straight from m-barcodes.mkiv \startPSTRICKS \pspicture(-4mm,-1mm)(38mm,26mm) \psbarcode{9781860742712}{includetext guardwhitespace}{ean13}% \endpspicture \stopPSTRICKS \stoptext ------------------------------------- log before the error: systems : begin file barcode-test-pstricks-0001 at line 1 system : module pstric loaded (/context/tex/texmf-context/tex/context/base/m-pstricks.tex (/context/tex/texmf-context/tex/context/base/m-pstricks.mkii !

Installing Context Minimals on Windows
by John Devereux 09 Jul '10

09 Jul '10

Hi, I normally use linux, but I now need to install context on Windows (7). Right now the minimals installation fails for me in various ways, depending on how I do it. Running the graphical installer I get two dialogs "update failed error code 1" and "make failed error code 1". Using the command line method I get a message about a vtable error when I try to run context. (It looked like the one mentioned in earlier postings, sorry I don't have the exact message now). I want just MKIV + extras (and intend to try TexWorks). Any hints appreciated. Thanks, -- John Devereux

Best version of ConTeXt
by Tom 09 Jul '10

09 Jul '10

What would be the best version of ConTeXt to recommend to a friend who writes novels on a PC running Windows? The person has no programming skills. He would probably require some assistance installing Tex-Live or whatever and would need a stable version because he couldn't manage frequent updates. Problems would far outweigh additional features for him. Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

writetolist causes mystery blank
by Michael Murphy 08 Jul '10

08 Jul '10

Hi all, I'm having a but of a problem using writetolist. In principle, I want to insert something into the table of contents, but I don't want to disturb the flow of the text. Unfortunately, the following code seems to generate a blank at the top of the page: \showframe \showmakeup \starttext \writetolist[section]{}{}% \framed{This box has been pushed down} \stoptext I've also tried using a section command where the output has been set to empty: \showframe \showmakeup \setuphead[section][ before=, after=, command=\mydonothing] \def\mydonothing#1#2{} \starttext \section{}% \framed{This box has been pushed down} \stoptext but that also gets me a blank. Incidentally, the same thing happens with writebetweenlist, (except that this seems to sometimes push content onto a new page for some reason). Any ideas? -- Michael Murphy
